Repeat the following procedure for the four given numbers.\
multiply the number by 2. add 4 to the product. divide this sum by 2. subtract 2 from the quotient.

the first number is 2. the result is ? ?

The first number is 2. It tells you to multiply by 2. This turns into 2x2. You will get 4 as an answer. It then tells you add 4 to the product. The product meaning the answer you got from multiplying the two numbers. This turns into 4+4. This is then turns out to be 8. It then tells you to divide the sum by 2. The sum being the number you got from adding the two numbers together. So this turns into 8/2. This will equal out to 4. Finally it tells you to subtract 2 from the quotient. The quotient being the number you got from dividing the two numbers. This is then turned into 4-2. You will get 2. So the final result is 2.
